Clearly, the 2 cameras offer different megapixel count and different sensor measurements. The G9 featuring a tinier sensor will make achieving shallow depth of field harder and the Sony A6600 will give you more detail as a result of its extra 4 Megapixels. Higher resolution will also enable you to crop shots a little more aggressively. The older G9 is going to be behind with regard to sensor innovation.
